# first install pgsql with home brew 
brew install postgresql

# at this point, you need to be sure you have /usr/local/bin before /usr/bin on your $PATH

# to see, run:
brew doctor

# if doctor does not complain about this issue you can pass this step.
# prepend /usr/local/bin to your PATH in your ~/.bash_profile
